clang-tidy selects toolchain?

As is known, clang can select another toolchain through:

clang --gcc-toolchain=/opt/gcc-7.3.0 -v

clang++ --gcc-toolchain=/opt/gcc-7.3.0 ¨Cv

Is there an equivalent option for clang-tidy?

Thanks.

I dont think so. What do you want to achieve? Clang-tidy will just build the AST from Code and do its analysis on it. I do not see a reason for a different toolchain.
